Type
Gonadorelin is a synthetic form of the naturally occurring gonadotropin-releasing hormone (GnRH). It stimulates the pituitary gland to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which in turn regulate testosterone production in men and ovulation in women. It is FDA-approved for diagnostic testing and fertility treatment. The pulsatile nature of GnRH secretion is critical for proper reproductive function.

Overview of Gonadorelin
Gonadorelin acts as an agonist of the GnRH receptor in the anterior pituitary. When administered in pulses (mimicking natural secretion patterns every 60-120 minutes), it stimulates release of FSH and LH. LH then stimulates Leydig cells in the testes to produce testosterone, or triggers ovulation in women. Continuous exposure paradoxically causes receptor downregulation and suppressed hormone production.
fertility and reproductive
- Treatment of conditions like Kallmann syndrome where GnRH deficiency causes low testosterone and infertility.
- Induces ovulation in women with hypothalamic amenorrhea who don't ovulate regularly.
- Stimulates testosterone and sperm production by restoring LH/FSH pulsatility.
- Treatment of delayed puberty due to hypothalamic-pituitary dysfunction.
diagnostic
- Used to assess hypothalamic-pituitary function and diagnose GnRH deficiency.
- Evaluates pituitary reserve and responsiveness to GnRH stimulation.
hormone optimization
- Maintains testicular function and fertility during testosterone replacement therapy.
- Helps restore natural testosterone production after anabolic steroid use.
- Treatment of undescended testes in pediatric patients.

PeptideGonadorelin Protocols
Can be administered as single injections or via pulsatile infusion pump. Single injections are used for diagnostic testing, while pulsatile administration mimics natural GnRH secretion for therapeutic purposes. Very short half-life (10-40 minutes) requires careful dosing strategy.
| Goal | Dosage | Frequency | Route |
|---|---|---|---|
| Diagnostic testing | 100 | — | SubQ or IV |
| Fertility support | 50 | 2 week range | SubQ |
| Pulsatile therapy | 5 | 90 week range | SubQ pump |
| TRT adjunct | 100 | 2 week range | SubQ |
Reconstitution Instructions
Materials needed:
Steps to reconstitute
- Clean work area and hands thoroughly
- Calculate required BAC water volume
- Draw BAC water into syringe
- Inject slowly down vial side (not directly onto powder)
- Gently swirl until dissolved (never shake)
- Store in refrigerator, use within 14 days
Gonadorelin Cycle
The Gonadorelin Cycle section explains how long a typical cycle lasts and what to expect during each phase. Over time, your body can become less responsive with continuous use.
Taking breaks between cycles may help maintain effectiveness and support better overall results.

Reconstitution Tips
- Use bacteriostatic water (BAC) — contains 0.9% benzyl alcohol for preservation
- Inject water slowly — aim down the vial wall, not directly onto powder
- Never shake — gently swirl or roll the vial until dissolved
- Store properly — refrigerate at 2-8°C after reconstitution
- Use within 28 days — most reconstituted peptides remain stable for about 4 weeks
- Keep sterile — always clean vial tops with alcohol before drawing

Frequently asked questions
What is a peptide dosage calculator?
A peptide dosage calculator is a free tool that converts your vial size, bacteriostatic water volume, and target dose into an exact syringe draw volume. Instead of doing the reconstitution math by hand, you enter three inputs and instantly get the concentration of your solution and how many milliliters or syringeunits to draw. This calculator works for single peptide compounds and multi-peptide blends.
How do I calculate peptide dosage from a vial?
To calculate your peptide dose, divide the total peptide content of your vial in micrograms by the volume of bacteriostatic water you added in milliliters. This gives you your solution concentration in mcg/mL. Then divide your target dose by that concentration to get your draw volume. For example, a 5mg (5,000 mcg) vial reconstituted with 2mL of BAC water gives a concentration of 2,500 mcg/mL. A 250 mcg dose would require drawing 0.1mL. This calculator automates all of those steps instantly.
How much Bacteriostatic water should I add to a peptide vial?
Most people add 2mL to 3mL of bacteriostatic water per vial, but the right amount depends on the dose you want to draw and the syringe size you are using. Adding 1mL to a 5mg vial gives you a concentration of 5,000 mcg/mL, making each dose very small in volume. Adding 2mL gives you 2,500 mcg/mL, which is easier to measure on a standard insulin syringe. A general guideline is to choose a volume that puts your typical dose somewhere between 10 and 30 units on a U-100 syringe. Use the calculator above to test different water volumes and find what works for your dose.
How are peptides different from proteins?
Both are made of amino acids, but peptides are much smaller than proteins. Because of their tiny size, peptides can act like tiny messengers in the body, sending specific signals to your cells to tell them exactly what to do.
